BCM (BODY CONTROL MODULE)
TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.
DTC Inspection Priority ChartINFOID:0000000001530554
DTC IndexINFOID:0000000001530555
NOTE:
Details of time display
 CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-
tion switch OFF → ON again.
 PAST: Displays when there is a malfunction that is detected in the past and stored.
 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
OFF → ON after returning to the normal condition if the malfunction is detected again.
